Mathematical Modelling of Steel Continuous Casting Hydrodynamics (1)
(Universitatea "Dunărea de Jos" din Galați, 2006)
The quality increase of steel continuous casting and a reliability indices of
afferent installations imposes the automation systems adoption of machines of
continuous casting of steel.
In this paper enters original ...
On the Kinetics of Sol Gel Al:ZnO thin Films Crystallization on Silicon Substrate
(Universitatea "Dunărea de Jos" din Galați, 2006)
Recently, there is a growing interest in applying ZnO thin films on silicon buffer
substrates for p-n junction devices, optical wave guide, etc.
A sol gel process is very attractive technique for obtaining oxide thin ...
Some Aspects Regarding the Elaboration of Multiple precessional Gear Theory and Modern Manufacturing Technology
(Universitatea "Dunărea de Jos" din Galați, 2006)
The engineering complex study of the triad “gear-technology-transmission” has
permitted to elaborate a new type of precessional transmissions with multicouple
gear. In this paper, the authors present the mathematic model ...
Protective and Decorative Vacuum's Coatings on Wares of Artistic Castings
(Universitatea "Dunărea de Jos" din Galați, 2006)
The problem of environmental protection is extraordinarily important, and its
actuality will increase with every year. In this aspect, processes of depositing of
coatings in vacuum have got serious advantages before ...
Research About the Vibration Parameters for a Cold Rolling Mill Machine
(Universitatea "Dunărea de Jos" din Galați, 2006)
By using the equipments of vibration measurement we can fight against the
damages (strip undulation and thickness variation on the length) who is show in
while of mill work. The amplitude of vibration parameters determine ...
Surface Hardening of 40Cr10 steel After Short Time Nitriding in Fluidized Bed
(Universitatea "Dunărea de Jos" din Galați, 2006)
The paper is based by nitriding in fluidized bed experiments over laboratory
plant. Fluidization applications are characterized by high values of mass and heat
transfer coefficients. For experiments were used 40Cr10 ...
Oxidizing Influence Over Surface Structures and Properties for A3k Steel Nitrocarburized in Fluidized Bed
(Universitatea 'Dunărea de Jos" din Galați, 2006)
Surface duplex thermochemical treatment (oxinitrocarburizing) has principal
scope to obtaining superficial mechanical higher properties with increasing
corrosion capacity. The paper is based by oxinitrocarburizing ...
Researches Concerning the Correlation of the Semiplanetary Rolling Process Factors
(Universitatea "Dunărea de Jos" din Galați, 2005)
An available solution of the elimination of the superficial cracks
network at the continuous cast slabs is the semiplanetary rolling. The
application of a semiplanetary rolling mill at the exit of slab from the curve
zone ...
Experimental Equation of Deformation Behaviour of a Concrete Steel
(Universitatea "Dunărea de Jos" din Galați, 2006)
The plastic deformation behavior is defined by the function of the deformation
strength according to the strain, strain rate and temperature as the factor of the
deformation process. The behavior law establishes by the ...
Establishing the Rolling-Friction Coefficient for Different Contacts Between Balls and Termochemicallly Treated Steel Rolling Paths
(Universitatea "Dunărea de Jos" din Galați, 2014)
Within the frame of this work, the influence of four very well-known and often
used thermochemical treatments (carburizing, carbonitriding, nitriding and
nitrocarburizing) of steel rolling paths applied on rolling-friction ...
